Only in your whacked out mind.
So this is what you keep hurling out there when you can't refute the actual argument. Let's try again, Sean.
MAJOR: Legitimacy of the V2 papal claimants is dogmatic fact.
MINOR 1: If someone rejects or doubts the legitimacy of the V2 papal claimants, he would be a heretic.
MINOR 2: +Lefebvre, +de Castro Mayer, and +Williamson have publicly expressed doubts about the legitimacy of the V2 papal claimants.
CONCLUSION: +Lefebvre, +de Castro Mayer, and +Williamson were/are heretics.
Archbishop Lefebvre: "While we are certain that the faith the Church has taught for 20 centuries cannot contain error, we are much further from absolute certitude that the pope is truly pope."
So Archbishop Lefebvre held that the legitimacy of the V2 papal claimants is less certain than the faith, i.e., that it's not nor has it been dogmatic fact. One can fill half a page with similar quotes of +Lefebvre saying the same thing, that SV is possible, that he doesn't say that you can't say they're not popes, etc. etc. If there legitimacy were dogmatic fact, that would preclude any doubt, and any possibility that the See might be vacant.
Try again, Sean. But this is typical of you. When you're completely refuted, you just start hurling childish insults. What a clown. You really should be embarrassed by your behavior.
